Potassium and Nitrogen Fertilization vs. Trace Element Content of Maize (Zea mays L.)

This research was conducted to study the impact of potassium and nitrogen fertilizers on trace element content maize (Zea mays L.). Higher doses fertilizer led a linear increase in cadmium, lead, nickel, zinc, manganese content, lower Fe:Zn Fe:Mn ratios. Moreover, cobalt level increased upon decreased higher potassium. The levels other elements (iron chromium) determined by dose and, particular, supply additional nitrogen. Potassium fertilization bioconcentration (BCFactor) most aerial parts maize. Nitrogen contents iron, ratios, Compared with potassium, produced less consistent changes factors for
